By Park Si-sooInternational football star Cristiano Ronaldo of Portugal will meet two Korean football prodigies and teach them some skills during his visit here on July 25.The two are Won Tae-hoon and Won Tae-jin, a teenage brother whose talent in football was known to the public recently through a popular TV program. Tae-hoon is known for scoring six a match on average in the domestic youth football league. The event was arranged by Korea Tech, which imports and sells Sixpad, an electronic muscle-building device. Ronaldo has been the device's promotional model since 2014. "We hope the brother will grow up as international football star like Ronaldo," a Korea Tech official said. Ronaldo will come to Seoul on July 25 via Japan. The primary goal of his visit is to promote the muscle-building equipment ― the football star will participate in a promotional event for the device, named Sixpad at a hall in Seoul on his arrival day. Born in February 1985, Ronaldo is widely considered one of the world's best football players.
